Abstract The theory of tune feedback correction and the principle a algorithm based on machine learning are introduced, with focus application lasso regression for correction. Simulation verification online results presented. show that, after applying learning, accuracy system was higher, betatron stability further improved.

The mutation rate was determined for mature sperm at eight specific gene loci on the third chromosome of Drosophila melanogaster using the low ion density radiations of 22 Mev betatron X-rays. A dose of 3000 rads of betatron X-rays produced a mutation rate of 4.36 X 10(-8) per rad/locus. Among the mutations observed, 66% were recessive lethals and 34% viable when homozygous. Only one of the 24 ...
